The Brands Behind Every Job
The quality of an electrical installation depends not just on the skill of the electricians carrying it out, but on the products used. Consequently, BW Henderson works exclusively with trusted, industry-proven suppliers for all residential, commercial, and industrial electrical work across Auckland. Furthermore, sourcing from established brands means our clients benefit from manufacturer warranties, compliant materials, and products that are built to last.
We have built long-standing relationships with leading New Zealand and international electrical suppliers — from cable manufacturers and switchgear specialists to lighting brands and automation suppliers. Below are the brands we work with across our residential, commercial, and industrial electrical services.
